Miles, 29, was arrested about 3:30 p.m. after Transportation Security Administration personnel discovered the weapon during an X-ray screening at the airport, according to information from a TSA spokeswoman and a jail official. Miles was arrested by St. Louis Airport police, then booked into the St. Louis County jail in Clayton later Wednesday evening.

It was unclear whether the loaded gun was found inside luggage or whether Miles had been carrying the weapon. The weapon was discovered at the Concourse A checkpoint. Authorities did not say what type of gun was seized.

Miles was booked about 8:30 p.m. on suspicion of unlawful use of a weapon, authorities said. He was to be booked and released pending application of a warrant on a formal criminal charge. He was not required to post bond.

Maybe just an honest mistake, but why does Darius Miles need to be carrying loaded guns around or anyway?
